[TrajX, TrajY] = ginput;
this has worked great but now does not work at all. I click mouse to select a region -- with simultaneous press of shift, or without -- and I get nothing. What is the problem? I have checked the Matlab help and documentation, but no clue how to use it

From the documentation: "[x,y] = ginput gathers an unlimited number of points until you press the Return key."
Did you press the Return key after clicking in the axes one or more times? The ginput function won't return, and won't assign any values to the outputs with which you called it, until you do.

If you want to return after clicking a single point, then try this:
again = true;
while again
[TrajX, TrajY] = ginput(1);
promptMessage = sprintf('Do you want to accept this point and Continue\nor re-do it and click the point again?');
titleBarCaption = 'Continue?';
buttonText = questdlg(promptMessage, titleBarCaption, 'Continue', 'Re-do', 'Continue');
if strcmpi(buttonText, 'Continue')
again = false;
end
end
